Usually it's a portion difference, not a disagreement. This page scores yam at a serving of 1/2 cup cooked (about 75g); at more than about 1 cup may raise FODMAPs it belongs in the high band. A source quoting the larger serve will call it high, and one quoting the smaller will call it low — the same food, measured at two different amounts.
